No Isolated Thunderstorms on Thursday

287

A chance of thunderstorms is decreasing as an upper level low is moving away from the island. An upper level low is an area of low pressure located in upper atmosphere.

The National Weather Service senior meteorologist Paul Stanko tells PNC news that a chance of thunderstorms increases as an upper level low causes a temperature difference from lower part of the atmosphere. 

It was located in west of the island on Tuesday, but it made its way to east by Wednesday. While it passed over the Marianas, it caused some lightening Tuesday night. 

“These features have been producing quite a convective outburst near and east of the Marianas with frequent lightning visible out to the east and northeast of Guam all night,” NWS explains.

Isolated thunderstorms are are expected tonight, but it might disappear tomorrow as an upper level low drifts farther away. A chance of rain remains 20% as usual, and east winds will prevail until Friday.

NWS further explains that the seas will stay moderate.

“Seas at the buoys have fallen slowly and are now 5 to near 6 feet. The rist of rip currents is moderate but may drop to low late Thursday or Friday.”
